KartoffelToby / better_thermostat

This custom component for Home Assistant will add crucial features to your climate-controlling TRV (Thermostatic Radiator Valves) to save you the work of creating automations to make it smart. It combines a room-temperature sensor, window/door sensors, weather forecasts, or an ambient temperature probe to decide when it should call for heat and automatically calibrate your TRVs to fix the imprecise measurements taken in the radiator's vicinity.

_TZE200_bvu2wnxz entity unavailable with local calibration #667

I was looking for SEA801/802 similar and found some which appear to be such a TVR https://www.kaufland.de/product/445477868/?vid=445477975 . But it is a ME167 which is not straight supported by Zigbee2MQTT. With this workaround https://github.com/twhittock/avatto_me167 it's possible but I can't integrate it properly with BT. It only works with target temperature calibration. With local temperature calibration its state is unavailable... Is this issue a problem due the missing Z2M support or the external converter or Better Thermostat or a combination of all?

wtom commented 1 year ago

Yes, if the local calibration is not available in Z2M, then BT can not work with that.

IvanRebroff commented 1 year ago

Okay, but the external converter provide this. In Z2M I can manually set the local calibration...

IvanRebroff commented 1 year ago

It was my fault: "Anti-Scaling" was disabled in the Z2M-Settings. When it's on the local calibration works!

wtom commented 1 year ago

Just out of my interest. What attributes do you get with this TRV? Does it also has an attribute for the heating state? And what tolerance does it have, for example the room is 19 degrees and you set the target to 20. Does it open the valve?

IvanRebroff commented 1 year ago

Yes it open the valve if the difference is just 1 degree.
